Of course it would “do the job” but you are wasting a lot of money.
Use an online calculator to figure out sizing. I don’t think you will need anywhere near that big of a wire. http://www.freesunpower.com/wire_calc.php |

Thanks for the link! All the calculators online i have found online have asked for the draw of the circuit not the supply of the panels.

The max feed from the panels is the number you want. How many amps can the panels push. If you can up the voltage the amps go down, along with wire size. It’ll be nowhere near 2/0.

I was looking at the problem from the wrong end I was looking a inverter not the panel output. so with the new figures I'm getting its 800 watts @ 48 volts =16.6 watts so a 2 AWG AL service wire should do the trick with no issues. So I need to get two more panels and the needed wiring. Thanks again
